RAILWAY-BUMPER.

SPECIFICATION forming part of Letters Patent No. 759,113, dated May 3,1904.

Application filed June 20,1903.

To all whom t may concern,.-

Be it known that I, GEORGE H. KIMBALL, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Railway-Bumpers, ofwhich the following' is a speciiication, reference being' had therein tothe accompanying' drawings.

The invention relates particularly to a bumping-post adapted to bearranged at the end of a track on the main line of a railway; and itconsists in the novel construction of the post and in the peculiararrangement and combination of its parts, as will be hereinafterdescribed, and particularly pointed out in the claims.

In the drawings illustrating my invention, Figure 1 is a view inelevation of the post. Fig. 2 is a plan view, Fig. 3 is a sectionalfront elevation, and Fig. 1 is a detached perspective view, of a sectionof the post.

In the drawings thus briefly described, A represents the usual rails,and B the post, arranged in connection with the rails in a manner to bepresently described. The post, as shown, is preferably, though notnecessarily, sectoral in configuration, comprising vertical and basesections C and D, respectively forming the post sides and a curvedconnecting'- section E. The latter section or are portion of the postcarries at its upper end a transverse beam F, constituting a buffer, andat its lower end a similar beam G, of greater length than the buffer,adapted to rest normally upon the yielding support or base H. Inpractice the post is preferably composed of two spaced triangular metalframes I and J and a series of curved wooden sections, as K, bolted, asshown, to and between the curved portions a of the frames forming thearc. Each of the frames carries a bracket L, which form a support forand to which is bolted the buffer F. The post described is pivoted orhinged at the juncture of its sides, so as to rock in a vertical plane,and its rocking movement is yieldingly opposed by the base H, thepeculiar construction of which will be hereinafter set forth. Inpivoting the post for the rocking movement referred to l' preferablyemploy an serai No. 162,325. et) modal.)

anchor M, consisting of an anchor-plate O, embedded in the ground, andthe anchor-rods I), projecting vertically therefrom and each terminatingat its upper end in a fork 7. Transverse anchor members Q and R are alsoused, said members being' formed of rails or bars riveted at two oftheir ends, as at T, to the track-rails and terminating at theiropposite ends at points opposite the forks o. The metallic frames I andJ extend at the juncture of their sides within the forks I), and thepost-pivot is formed by a bolt T', which engages the metallic'frames,the transverse anchor members, and the forks. A spacing-collar c isinterposed between the forks, so that a rigid structure will beproduced.

The yielding base previously referred to may be formed in various ways,the preferable construction consisting of beams arranged in suchrelation to each other that they will be capable of springing 'orflexing, so as to produce the desired Opposition to the rocking movementof the post. In the drawings I have shown the base comprising' a seriesof beams U, arranged in a suitable pit or well U', and a similar' seriesV, arranged crosswise of the first series and spaced therefrom at theirends by planks W. X'reprcsents a third series of beams extending inparallelism with the beams U and separated at their ends from the series'V by planks W'. Upon this last series referred to the transverse beammember G of the post is adapted to rest, -the post member being spacedat its ends from the third series by planks or suitable boards P'.

It will be obvious from the construction of the device that upon therocking of the post its foot G will flex, and if asevere blow isimparted to the bumper the several series of planks beneath the footwill successively flex, and thus serve to yieldingly oppose the postsmovement.

I have shown and described a preferable form of rocking post wherein anarc-shaped section is employed as the connection between the post sides,as an arc for well-known reasons is best adapted to transmit to theyielding base the blows that the post receives. I do not wish, however,to be limited to the exact structure shown, as the mechanism is sus- IOOCeptible of various modificationswithout in any manner departing fromthe spirit of my invention.

What I claim as my invention isl. In a railway-bumper, the combinationWith a sectoral bumping-post fulcrumed at the ,juncture of its sidesindependent of the rails for vertical rocking movement, and means foryieldingly opposing said rocking movement.

2. In a railway-bumper, the combination of a yielding base or support,and a sectoral bumping-post fulcrumed at the juncture of its sides forrocking movement and having an end opposite the fulcrum contacting withthe base.

3. In a railway-bumper, the combination with a bumping-post comprisingvertical and base sections fulcrumed at their juncture independent ofthe rails for rocking movement, a bumper carried by the verticalsection, and a yielding support for the base end opposite the fulcrum.

4. In av rail\va\'-bumper, the combination with a bumping-post havingvertical and base sections connected at their meeting ends, and a bumpercarried by the vertical section, of vertical and transverse anchormembers pivoted to the post sides at their juncture, and a yieldingsupport for the end of the base-secd tion opposite the pivot.

5. In a railway-bumper, the combination with a sectoral bumping-postfulcrumed at the juncture of its sides, for rocking' movement, andcarrying transverse beams at the opposite ends of its arc, and ayielding support upon Which one of the beams is adapted to rest.

6. In a railway-bumper, the combination of' a vertical member fulcrumedindependent of the rails for rocking movement, an arcshaped sectionsecured at one of its ends to said member, and means in operativerelation to the opposite end of the arc for yieldingly opposing' itsrocking movement.

7. In a railway-bumper, the combination of a yielding base, a verticalmember fulcrumed in advance of the base for rocking movement, and anarc-shaped section rigidly secured at one end to the upper portion ofthe vertical member and having its opposite end supported upon the base.

. In testimony whereof I aiX my signature in presence of two Witnesses.
